Cathcart Tower stands on Cedar Island in the St. Lawrence River, one of four Martello towers built in 1846 to defend Kingston's harbour. Unlike its land-based counterparts, this tower requires a boat to reach, adding a sense of adventure to the visit. The tower's thick limestone walls and original features, such as the gun platform and vaulted rooms, are well preserved. Visitors can explore the interior and learn about its strategic importance during the mid-19th century. The island itself offers a quiet setting with views of the water and passing ships, making it a unique destination for history buffs and nature lovers alike.
